🌿 Even, fine grind
Sharp stainless steel teeth slice your herbs cleanly without crushing them, delivering a uniform texture that maximises aroma release.
⚙️ Built-in pollen catcher
The fine mesh screen separates the most valuable trichomes into a dedicated chamber. Collect pollen progressively for a premium touch.
🛡️ Tough magnetic lid
Aerospace-grade aluminum with magnetic closure: no spills, safe transport and a long lifespan even with daily use.
A 4-part grinder adds a screen and a pollen chamber underneath the grinding chamber. Your herbs are ground at the top, then the finest pollen falls through the mesh and collects in the bottom compartment. Ideal for users who want to capture trichomes.
How do I clean my aluminum grinder?Disassemble the 4 parts and brush them dry with a small soft brush (or a toothpick) to remove residue. Avoid water, which can oxidise aluminum. A clean every 10-15 grinds keeps the teeth sharp and the grind optimal.
With its 50 mm diameter and pollen catcher, this BloomLED grinder offers the best value for daily use — durability, fine grind and discreet operation in one tool.
